404 error for front office - back office works

[Atilla_the_hun]

Problem:
My back office seems to be working.
My front office does not work. When i click on view my shop i get the following error:

"404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable."

I have created a .htaccess file that was blank. The generate friendly url / optimise worked.

The config / settings.inc.php / is set as follows: define('__PS_BASE_URI__', '/');

when i go to load my domain.com it automatically goes to domain.com/en

Any ideas would be appreciated

Thanks

EDIT:
ok. I went to the back office / preferences / SEO & Urls and turned off the automatically redirect to Canonical url. This allowed me to open the front office.

I am having th same problem with the products. the link try to launch domain.com/en/product. How do i remove the en?

The products would not open when i clicked on them. So i turned off the friendly URL.

How do I turn on friendly URL's and not loose the links?

copy the above code to your .htaccess file.

The back office is now working.

The home page on the front office works, however all the images from the products are not showing and the links to the products returns a 404 error.
